translation Flashcards
1
Q
1.nuclear pore
A
mrna is released to dna and passes out of nucleus through nuclear pore to cytoplasm
2
Q
- ribosome attachment site
A
ribosomes have two attachment sites for tna
one for trna that already has an amino acid, one carries the next aa in the sequence
smaller mrna attachment site with anticodon
3
Q
3.trna and amino acid
A
atp activated amino acid is attached trna molecule
4
Q
4.base pairing
A
trna attaches itself to mrna by complementary base pairing
trna for first codon binds to larger subunit, trna for second binds to 2nd attachment site
5
Q
5.peptide bond
A
amino acids on trna molecules join by peptide bond by ribosomal enzyme
6
Q
6.trna….
A
trna detaches from amino acids
7
Q
7.repeat
A
process repeats and a polypeptide chain is formed until a stop codon is reached
